I have on 07 X. Just below the ignition keyhole (or whatever you call the place where you stick your key in to start the engine) is like a rubber piece that sticks out a bit? Sorry, I don't have a pic, but it looks like it was implemented with only the 07's. The 05's and 06's don't have it according to my knowledge. Is it just a piece of rubber for protection to maybe prevent the keys from hitting that part and possibly scratching it?
